O 4 l v5 Patented May 24, 1932 UNITED STATES PATENT OFFICE GEORGE E.NICHOLS, OF ABBEVIFLLE, ALABAMA, ASSIGNOR, IBY DIRECT AND MESNEASSIGNMENTS, TO THE WONDER SKIDDER COMPANY, INC., 0F ABBEVILLE, ALA-BAMA, A CORPORATION OF ALABAMA HAULING DEVICE Application filed March31, 1930. Serial No. 440,351.

The invention relates to a hauling device to be attached to and used inconnection with the ordinary motor vehicle truck.

The object of the invention is to provide a 6 hauling device which isportable and may be quickly and easily attached to or detached from anymotor truck without alteration thereto.

Another object of the invention is to provide-a hauling device whichderives its power from the traction wheels of the motor truck withoutinstallation of driving connections between the truck wheels and thehauling device.

Another object of the invention is to provide a hauling device which isadapted to exert a slow and powerful pull or a fast and less powerfulpull.

Still another object of the invention is to sturdy in construction,eflicient in operation, lasting in quality, and comparativelyinexpensive to manufacture.

With these and other objects and advantages in mind, attention is calledto the drawings, in which:

Figure 1 is a side view of the hauling device in operative positioninstalled on the floor of an ordinary truck.

Figure 2 is a plan View of the hauling device as shown in'Figure 1,

Figure 3 is a sectional view of the winding drum of the hauling devicetaken on the line 33 of Figure 2, and

Figure 4 is a sectional View of the means for shifting the haulingdevice into and out of operative engagement with the traction wheels ofthe truck, taken on the line 4L4 of Figure 2.

Referring more specifically to the drawings, in which like numbersindicate like parts, 1 is the frame and 2 is the floor of an ordinarytruck having front wheels 3 and rear driving wheels 4 and a drivingshaft 5 from the motor to the rear wheels.

The hauling device which forms my inven tion comprises a frameapproximately the width of the floor of the truck having sides 6, ends7, and provided with cross bars 8, all of which are preferably cast,although the parts provide a hauling device which is simple and namedmay be joined to each other in any of the well-known ways. It will benoted that the ends of the sides 6 are rounded off as at 8, the purposeof which will be later explained.

Pivotally attached to both sides of the frame near the ends thereof, byany wellknown means, such as a bolt 9, are strap like metallic members10 having at their lower ends slots 11. When the frame of the haulingdevice has been correctly positioned on the floor of a truck, the slots11 will cooperate with the bolts 12 attached to the sides of the truckframe and prevent any lateral movement but will allow longitudinalmovement of the hauling device.

Mounted on top of both sides of the frame of the hauling device in anysuitable manner are members 13 provided with two upward projections 14and 15 having holes 16 therein to accommodate the shafts of the haulingmechanism.

In the holes of the front projections 14 is mounted for rotation a shaft17 provided at one end with a gear wheel 18 feathered to said shaft,which is held against displacement in any suitable manner, such as bynuts 19. Feathered to this shaft 17 and movable therefrom is a windingdrum 20 with cable In the holes of the rear projections 15 is mountedfor rotation a shaft 22 provided at one end With a gear wheel 23 whichmeshes with the gear wheel 18, and at both ends with flat pulley wheels24 feathered to said shaft and held against displacement in any suitablemanner, as by nuts 25. I

By removing the nuts or other means at either end of the shafts they maybe withdrawn and the winding drum interchanged from one shaft toanother, or larger or small er gear wheels and pulleys may be attachedas desired, to suit the purpose to which the device is applied.

At the front end of the hauling device there is provided the means forshifting the mechanism into and out of engagement with the tractionwheels of the motor truck. Attached to the front end 7 and the frontcross bar- 8 is a plate 26 having a slot 27 therein. A

ratchet- 28 is bolted or otherwise attached to the floor of the truckand has pivotally and detachably secured thereto at 29 a handle 30provided with a spring operated pawl 31 to cooperate with the ratchet,thereby holding the handlein a setposition. The handle is enlarged at 32to withstand the pressure exerted against the plate 26 when the'handl-eis moved-back and forth.

To-install the hauling device itis necessary only to screw the bolts 12at the proper distance on each side of the truck frame and to attach theratchet 28 near the front end of and in a central position on the floorof the truck. Due to the fact that the ratchet is near the forwardend-of the truck floor itin many instances can be left permanentlyattached thereto. as it is notlikely to interfere in any use to whichthe truck is put. when not carrying the hauling device. Likewise,

' thebolts on the sides of the truck frame need notbe-disturbed whenonce attached.

-Thehauling device is then secured upon the t-ruckfioor by thestrap-like members with the slots 11 engaging the bolts 12. The

handle isthen dropped through the slot 27 in'plate 26 and pivotallysecured at 29 to the ratchet 28.

Due to the rounded off portions 8 of the ends of the sides 6 0f thehauling device frame, it will easily move back and forth on the truckfloor even though, throug-huse, the truck floor may be rough and uneven.

. Theoperation of the device afterinstallation-is extremely simpleand-may be accomplis-hed either while the truck, isjacked up in anywell-known manner, as shownin Figure 1, orwhile thetruck ismoving underits own power. By simply operating the handle backwardly the fiat pulleywheels will come 'into contact with the tires of the traction wheels-ofthe truck and-power will be transmitted through the gears to the windingdrum. and cable thereon. By simply operating the handle forwardly theflat pulley wheels. are disconnected from the traction wheels'o-f thetruck and operation of the hauling device stops.

. If a light load is to be hauled, the drum and cable may be transferredin a few minutes from shaft 17 to shaft 22 and in so doing greatrapidity in hauling can be obtained, as the latter shaft revolves morequickly than the former shaft.

Ill-order to accommodate differently sized tract-ion wheels and tires onthe motor truck, differently sizedflat. pulley wheels are provided; forattachment to shaft 22, and it is of course, possible to obtain anygearing ratio desired between the two shafts 17 and 22.

-Actual:use of the hauling device under all kindsof conditions andin allkinds of operations has shown very successful results in.

that there is provided sufiicient power to haul the heaviest ,of loads.Because of its portable nature and without the necessity of altering themotor truck in any Way to be adapted to receive the hauling device, theinvention fulfills a long felt need where devices of this type arenecessary.
